but as you see from the link over, you would not hinder any one that downloads file trough anything else but internet explorer.

I already configured that using group policy. But in that when we try to download a file, it will ask for optionas open, save, cancel. When I click save........... that will show the msg your security setting is blocked this.
But if I click on open,............. that will first download and will open. I want to block that also.
